Abstract

The embodiment of the invention discloses a method and device for sending or receiving a physical uplink control channel PUCCH. The method comprises the following steps: a terminal device receives a physical downlink control channel PDCCH from a network device, the PDCCH is used for indicating that the terminal device to send the PUCCH, indicating the time frequency resources used by the terminaldevice for sending the PUCCH and subcarrier intervals; and the terminal device sends the PUCCH to the network device on the time frequency resources according to the subcarrier intervals. According tothe method for sending the PUCCH in the embodiment of the invention, the terminal device determines the transmission of the PUCCH according to the PDCCH sent by the network device, and determines thetime frequency resources and the subcarrier intervals used for sending the PDCCH according to the PDCCH, thus solving the problem of how to send the PUCCH in a communication system with multiple subcarrier intervals.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending or receiving a Physical Uplink Control Channel (PUCCH). Background technique [0002] In traditional digital signal transmission, the information flow is transmitted through one channel at a time, which belongs to the serial transmission method. The multi-carrier technology adopts the parallel transmission method, which converts the serial high-speed information flow into parallel and divides it into multiple parallel low-speed information flows, and then superimposes and transmits the multiple parallel low-speed information flows to form a multi-carrier The transmission system, that is, the multi-carrier technology is a technology that uses multiple carriers to transmit high-speed data information. Among them, the carrier is the radio wave of a specific frequency carrying data. [0003] Multi-carrier transmission technology has been widely used...
